SVP3000: High durability and stability Isolated design between electronics and pneumatic circuits

  This design eliminates troubles caused by dusty and humid air quality.

Instrumentation air and outside atmosphere do not come into the electronics circuit department.

Pneumatic circuits

Even if the atmosphere is corrosive and instrumentation air is not perfect, it does not affect the electrical part of the positioner.

Electronics circuits Isolated design between electronics and pneumatic circuits
